示例1: async
async () => {
const { stdout } = await execa('stdin', {
input: 'hello',
stdio: [null, 'ignore', null]
});
assert(stdout === null);
};示例2: async
const getSsim = async ({ toolName, imageName }: ISubject) => {
const original = getPath({ toolName: 'photoshop', imageName });
const optimised = getPath({ toolName, imageName });
const { stdout } = await execa('pyssim', [original, optimised]);
const ssim = parseFloat(stdout);
return ssim;
};示例3: log
.then(exists => {
log('found %s ?', exePath, exists)
if (!exists) {
throw notInstalledErr(`Browser ${name} file not found at ${exePath}`)
}
// on Windows using "--version" seems to always start the full
// browser, no matter what one does.
const args: [string] = [
'datafile',
'where',
`name="${doubleEscape(exePath)}"`,
'get',
'Version',
'/value'
]
return execa('wmic', args)
.then(result => result.stdout)
.then(trim)
.then(tap(log))
.then(getVersion)
.then((version: string) => {
log("browser %s at '%s' version %s", name, exePath, version)
return {
name,
version,
path: exePath
}
})
})示例4: cache
const getLatLon = cache('latlon', async () => {
debug('fetching lat/lon...')
const { stdout } = await execa('whereami')
let lines = stdout.split('\n')
let lat = (lines.find(l => l.startsWith('Latitude:')) as string).split(': ')[1]
let lon = (lines.find(l => l.startsWith('Longitude:')) as string).split(': ')[1]
return { lat, lon }
})示例5: _spawn
// eslint-disable-next-line no-underscore-dangle
function _spawn(command, args, opts) {
children += 1;
const child = execa(command, args, opts);
const drain = (code, signal) => {

return child;
}示例6: getVersionString
export function getVersionString(path: string) {
const doubleEscape = (s: string) => s.replace(/\\/g, '\\\\')
// on Windows using "--version" seems to always start the full
// browser, no matter what one does.
